The Teco FireBag® automatically turns off gas supply in the event of fire, preventing explosions and the spreading of fire. When outside temperature reaches 203°F to 212°F (95°C to 100°C) the metal alloy that keeps the plug and cartridge together melts and the spring pressure pushes the plug against the gas opening to close it completely. No fire or heat detectors are required to automatically intercept gas flow.  Please see the available options for these thermal-activated shut-off devices for use with natural gas, propane, and butane.

DESIGN

Boehmer fully welded ball valves meet the requirements of the most common national and international standards.

FIRE PROTECTION

When fire safe certification is required, Boehmer can produce a range of valves to API 6FA, API 607 and BS 6755 P 2.

TRUNNION MOUNTED BALL

The standard design of Boehmer ball valves provides a trunnion mounted ball for pressure class ANSI150 starting at 6 inch and ANSI300 and above at 3 inch size. The maintenance-free bearings for stem and trunnion are self-lubricating, thus assuring a lower torque especially for high pressure ratings.

ANTI-STATIC DEVICE

When required, the ball valve design includes an electric conductive connection between the internal parts of the ball valve and the body providing the anti-static function.

STEM SEALING

The sealing of the stem to the atmosphere is achieved by up to three independent sealing systems. The stem sealing design ensures the anti-blow-out function. Some valves can be produced with a design of the stem assembly, so the seals are replaceable under full pressure in either open or closed position.

EMERGENCY SEALING

As an option, Boehmer ball valves can be delivered with an additional emergency sealing injection for the seat-rings and/or stem sealing.
